A friend of mine who is'nt the most experienced Mac user has done something to his Mac, Safari in particular I think and now he can only load secure websites (https) everything else comes back as page not found. Anyone have any ideas on what he could have messed around with to do this and more importantly what to do to sort it out? Any help would be greatly appreciated. Thanks

Has your friend set up an HTTP proxy, by any chance? This would be set in your Network control panel. If that proxy is set to a random address, it would explain why HTTP doesn't work but HTTPS does.

As another question: have him try each site twice. If it works the second time, then it's a problem we've seen before, and we can help with that.
